Storage, bro. Look for adequate storage. Lots of/most new homes have crap for storage. Look for good closets and lots of them(hall, bath, and bed).
Also, watch out for mold. Most dumbass builders don't protect the home from mold property by putting the vapor barrier(plastic sheeting) on the correct side of the insulation. Go into the basement and see if you can find unfinished areas with insulation showing. If the plastic is on the inside, you may eventually have mold issues. This is going to be a huge epidemic in our generation. Too many shitty houses built in the '90's and 2000's w/ bad code enforcement. If you ask your realtor about this, they will tell you that there are two schools of thought on this. Don't listen to that crap. Either it's right or its wrong, and if wrong, they don't prevent anything...they actually increase the ability for mold to grow.
Also, look for adequate drainage. Sounds Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!), but make sure that the ground slopes away from the home so that water doesn't run to the house.
